GET and POST methods

GET and POST

One thing we ignored in our discussion about forms was that the METHOD

by which the form is submitted may be one of the two: GET or POST.

When to use GET?

Any data that you pass via a GET can be retrieved in your script by using the

Request.QueryString collection. GET may be used for small amounts of data

– the reason being that, the data items are appended to the URL by your

browser, and obviously, you cannot have an infinitely long URL (with the

QueryString).

When to use POST?

Almost always. Stick to POST for your forms, and be sure to use the

Request.Form collection to access them (and not the Request.QueryString

collection.)
